About Pascal
Definition: The pascal (symbol: Pa) is the SI unit of pressure, defined as one newton per square meter of force applied perpendicularly.
History: Named after French mathematician Blaise Pascal in 1971. Adopted as standard SI pressure unit replacing various national standards.
Current Use: Universal scientific and engineering pressure unit. Used in meteorology, materials science, and precise pressure measurements.
Examples: Sound pressure: 20 μPa, blood pressure: 10-20 kPa, vacuum systems: 1-1000 Pa, material stress: MPa range
About Torr
Definition: The torr is a unit equal to 1/760 of standard atmospheric pressure or approximately 133.32 pascals.
History: Named after Evangelista Torricelli, inventor of the barometer. Defined as 1 mmHg in vacuum applications.
Current Use: Standard in vacuum technology, laboratory equipment, and applications requiring precise low-pressure measurements.
Examples: High vacuum: <10⁻³ Torr, rough vacuum: 1-100 Torr, laboratory pumps: 10⁻⁶ Torr, mass spectrometry: 10⁻⁹ Torr
